THOMAS J. L. SMILEY AND CHARLES H. STOMBS, OF SAN FRANCISCO, CAL.

AUTOMATIC LAMP-EXTINGUISHER AND WlCK-TRIMMER.

SPECIFICATION forming part of Letters Patent No. 290,607, dated December18, 1883.'

Application filed May 21, 1883.

To all whom it may concern:

Be it known that we, THOMAS J. L. SMILEY and CHARLES H. SToMBs, both ofSan Francisco, in the county of San Francisco and State of California,have invented a new and Improved Automatic Lamp-Extinguisher andWick-Trimmer, of which the followingis a full, clear, and exactdescription.

Our invention relates to automatic lamp-ex- IO tinguishers andwick-trimmers; and it consists in the peculiar construction andarrangement of the parts, as hereinafter more fully set forth, andpointed out in the claims.

Reference is to be had to the accompanying I 5 drawings, forming part ofthis specification, in

which similar letters of reference indicate corresponding parts in allthe figures.

Figure 1 is a side elevation of a wick-tube on which a pair ofextinguishing claw-plates are pivoted to a removable support adapted tobe fitted on the wick-tube, so that the wick will have power to openthem when thrust up by the wick-adjuster, and which will fall togetherby gravity or spring-pressure over the wick and extinguish it when thewick is pulled down. Fig. 2 is a sectional elevation of Fig. 1 on line00 00. Fig. 3 is a side elevation of a modified form of the devicerepresented in Figs. 1 and 2, and Fig. 4 is a section of Fig. 3 on lineto w.

We propose to have two plates, at, to close over the wick-tube b byturning on pivots c, as in Figs. 1 and 2, or to spring over the tube, asin Figs. 3 and 4, inclusive. When the 3 5 plates (1, pivoted at cin theremovable support, are employed, the distance from the pivotal point 0to the upper end of each plate a is greater than from the pivotal point0 to the lower end of each plate a, so that when the (ModeL) wick-tubeis held vertical (its normal position 0 when in use) the upper ends ofthe plates a, above their hinges, will be heavier than their lower endsbelow their pivotal points 0, and when the wick is drawn down by thewickadjuster below the plates (1, the latter will fall 5" on the upperend of the wick-tube by gravity, extinguish the light, and trim thewick, and both these results are obtained automatically.

In the arrangement of Fig. 1 the plates are opened by the push of thewick against them when it is raised by the ratchet, and they close bygravity when the wick is lowered.

Having thus described our invention, we claim as new and desire tosecure by Letters Patent- 1. The combination, with a wick-tube, of aremovable frame provided with an aperture to receive said tube, andcarrying plates which are adapted to be opened by the wick in raisingit, and so pivoted to the frame as to fall by gravity, whereby they areautomatically closed when the wick is lowered, substantially as shownand described, whereby the lamp is automatically extinguished andtrimmed, as set forth.

2. An improved article of manufacture, consisting of a frame providedwith an aperture adapted to fit over a lamp-wick tube, and provided withplates (1, so pivoted to said frame as to fall by gravity, whereby theyare automatically closed when the wick is lowered, substantially as setforth.
